echo

Use this command to configure echo packet settings.

Syntax

echo {min-tx interval | min-rx interval | miss-count number}
no echo {min-tx | min-rx | miss-count}

Parameters

min-tx interval Specifies the minimum interval in 50ms increments between the transmission of echo packets. Valid values are from 50 - 10000ms. The default value is 250ms.
min-rx interval Specifies the minimum interval in 50ms increments between the transmission of echo packets by the neighbor.

Valid values are from 50 - 10000ms. The default value is 250ms.

miss-count number Specifies the minimum number of consecutive echo packets that can be missed before the BFD session transitions to down. Valid values are 1 - 100. Defaults to 3 consecutive packets.

Defaults

  • The min-tx interval defaults to 250ms
  • The min-rx interval defaults to 250ms
  • The minimum number of missed consecutive echo packets defaults to 3

Mode

BFD probe configuration mode.

Usage

The “no” option resets echo packet settings to default values.

Examples

This example shows how to set the minimum transmit and receive intervals to 350ms and the minimum number of missed consecutive echo packets to 5 for BFD probe bfdProbe1:

System(rw)->configure
System(rw-config)->probe bfdProbe1 bfd
System(su-config-probe-bfd)->echo min-tx 350 min-rx 350 miss-count 5
System(su-config-probe-bfd)->
